Historical reciprocal tariff for CM-origin goods

A “historical reciprocal tariff for CM-origin goods” is an import measure recorded under the International Emergency Economic Powers Act (IEEPA). “Reciprocal” generally means an additional tariff intended to respond to trade barriers or conditions associated with the exporting country. “CM-origin” is an origin code used in the official trade data; confirm which country or territory that code represents before relying on the record.

This type of measure typically affects goods whose country of origin is the specified country and whose tariff classification falls within the measure’s product scope. “Historical” means the record concerns a past period or prior version of the measure, so it should not automatically be treated as a currently collectible duty. It matters because an additional duty may have applied on top of the ordinary HTSUS duty and other import charges, depending on the entry date, product scope, and any exclusions or exceptions.

What to check

• Confirm what the CM origin code means and determine the product’s legal country of origin under U.S. customs rules; do not rely only on the shipping country.
• Verify the product’s complete HTSUS classification and compare it with the measure’s covered tariff provisions, descriptions, and exclusions.
• Check the measure’s status and effective period against the entry date, because a historical record may no longer apply or may apply only to earlier entries.
• Determine whether the tariff is an additional duty layered onto the normal HTSUS rate and review how customs instructions describe reporting and payment.
• Keep supporting records for origin, classification, valuation, and eligibility for exclusions; ask a licensed customs broker or trade counsel to resolve ambiguous cases.
